It had enormous problems with the hydraulic launch system before it opened. It took weeks of testing to get it to its top speed because the hydraulics were only launching the trains at 128 mph (ironically) (On hydraulic launch coasters they go from low speed to top speed during testing, and it wouldn't go past 128). They resolved the issue, and I don' think it's had mechanical issues since.
I never understood the whole "top speed" thing for this coaster. It reaches 149 then immediately goes into trims which bring it down quite a bit. It's only the world's fastest coaster for less than 5 seconds.
Also SFGAdv still markets KK as the world's tallest and fastest lol.
